ISAAC RASKIN, OF NEW' YORK, N. Y.

BREAD-MIXER.

Application filed. August 23, 1919.

To all whom t may concern:

Be it known that I, ISAACRASKIN, a native of Russia, who has declared his intention of becoming a citizen of the United States, residing in the borough of Manhattan, in the city, county, and State of New York, have invented a new and useful Bread-Mixer, of which the following is a specification.

The invention is an improved power-operated bread-mixing machine. A feature of novelty is a safety stop whereby the power can be thrown off the rotary paddle either from the top or from the front of the machine. Heretofore these machines have been equipped with stops operable by a person on the floor, but inaccessible to an attendant standing` on a bench leaning over the receptacle, whose arm may have been caught by the paddle. Serious accidents have occurred in this way, which it is the object of the present invention to avoid by enabling the attendant in such case to release himself; at the same time the lower stopping station is preserved, the construction being such as' to combine two stops in one mechanism of a simple and positive character, compactly disposed with respect to the adjacent parts of the machine.

At one side the machine herein disclosed has a gear standard provided with an inclosure for the gearing which coincides with the standard itself. The receptacle is furnished with a sliding sectional c over.

In the drawings:

Figure 1 is a rear perspective of the machine;

Fig. 2 is a front elevation, showing the receptacle tilted forward, and a portion of the gear standard inclosure broken away;

Fig. 8 is a sectional side elevation, the plane of the section passing through the gear standard inclosure;

Fig. 4: is a plan view of the cover for the receptacle Fig. 5 is a side view thereof;

Fig. 6 is an enlarged detail section on the line 6-6 of Fig. 3; and

Fig. 7 is a similar view on the line 7 7 of Fig. 4.

The machine frame comprises a flat base 1, with a gear standard 2 at one side and a tail standard 3 at the other side. A receptacle 4 of usual rectangular form with troughed bottom is swung between the standards on a horizontal axis so as to be tiltable in the customary manner.

about the same axis. A front curtain wall 6 rises from the base to the height of the lower I part of the receptacle. The receptacle can be tilted by a worm 7 on the gear standard, operated by a hand-wheel 8 in front, and meshing with a gear segment 9 united with the receptacle, all as is well known.

The paddle is driven Vfrom an electric m0- tor 10 on the base adjacent the tail standard. A pinion 10a on the motor shaft drives a large gearll on one end of a shaft 12 eX- tending between the standards. The teeth of the gear 11 are covered by an inturned marginal flange 13 on the standard 3.

On the opposite end of the shaft 12, which passes through an opening 14 in the standard 2, is a pinion 15 meshing with a large gear 16 fixed to the shaft 17 on one end of the paddle. The pinion 15 is free on the shaft 12 and can be coupled and uncoupled -rearward at a steep inclination, from the upper forward part 0f the standard to the vicinity of the clutch. The means for operating the rock-shaft comprises a two-armed arched lever 21 secured at its central or intermediate portion to the upper end of the shaft, whence it extends upward and rearward, in one direction, to the top of the standard, and downward and forward, in the other direction, to the front. At the two regions the lever bears projecting handles 22, 23, for the purposes previously indicated. rllhe arrangement of the lever, closely following the rounded periphery of the upper part of the standard spaced slightly from the side of the receptacle, makes for compactness of the machine and enables the lever to clear both parts when thrown throu l a slight arc, to couple or uncouple the clutx.

The standard 2 is stift'ened by an outwardly directed marginal flange 24:, onto which tits a hollow cover 25, housing the driving and tilting gearings. This cover duplicates the contour and area of the standard, constituting in effect a removable boxed extension thereof. The cover is held in place by screws 26, and is preferably made in two parts meeting at the vertical junction 27, so that the rear and smaller section can be removed alone to give access to the interior.

Upon the arched tops of the side walls of the receptacle, angles 28 are secured by screwed straps 29, so as to form inwardlyopening channels 30, in which slide the side edges of a cover 3l. Said cover is formed of a plurality, preferably three, sections 81a, 31h, 3l, in overlapping or shingled relation. The sections are flexibly connected by pivotally jointed toggle links 82, pivoted to raised strips 33, which are secured along the rear edges of the sections. .At the joint of each toggle a stop 34k is bent up the end of one link to coperate with the side of the other, thereby preventing the links being straightened, so that the cover will always slide back freely. A hook 35 on the rear .edge of the rearmost section takes over a flange 37 on the back of the receptacle at the top, and on the front of the foremost section is a handle 38. The linkage is so proportioned that when the sections are pulled forward as far as permitted by the stops, the opening of the top is completely covered. When the cover is pushed back as seen in Fig. 2, it collapses to the width of a single section, leaving a large opening. The links are so arranged as not to interfere in the collapsing operation.

What I claim as new is:

l. In a bread-mixer having a frame, a receptacle swung therein on a horizontal axis, a paddle rotatable about the horizontal axis, and mechanism including a clutch for driving the paddle: safety stopping means comprising a rock-shaft controlling said clutch, and a two-armed lever on the rock-shaft having handle portions at the top and at the front of the machine.

2. In a bread-mixer, and in combination with a frame including a gear standard, a receptacle swung on a horizontal axis in the frame, a paddle rotatable about the horizontal axis, and mechanism including a clutch for driving the paddle: a rock-shaft en the gear standard extending steeply downward and rearward from the upper front region to the vicinity of the clutch, an arched lever secured at the middle to the upper end of said shaft and clearing the periphery of the standard in adjacent spaced relation to the side of the receptacle, and handles upon both ends of the lever.

3. In a bread-mixer, the combination with a frame, a receptacle swung therein, a paddle in the receptacle, and means including a clutch for driving the paddle, of a laterally movable two-armed lever pivoted at the upper' forward part of the frame at one side of the receptacle with one arm extending rearward for operation at the top of the machine and the other extending downward for operation at the front, and connections between said lever and the clutch.

'-l. ln a bread-mixer, the combination with a frame, a receptacle swung therein, a paddle in the receptacle, and means for driving the paddle, of a stopping device on the frame at one side of the receptacle near the top of the machine accessible to an attendant leaning over the interior, and means operable by said device for stopping the rotation of the paddle.
